最近因爲有個工做任務須要搭個虛擬機環境，可是環境是搭建在內網，沒法直接聯網，不少軟件都不能直接yum安裝，html

安裝過程實在十分不順利，在此留個記錄給有須要的朋友。python

環境是 CentOS 5.7 x64mysql

 

請選擇合適的方式，下載python2.7.3安裝包linux

http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
 
安裝前固然須要編譯器gcc
 
  1. yum install gcc  
yum install gcc
爲了安裝setuptools，要須要安裝zlib
 
  1. yum install zlib zlib-dev  
yum install zlib zlib-dev
解壓安裝python2.7
 
  1. tar jxvf Python-2.7.3.tar.bz2 
  2. cd Python-2.7.3 
  3. ./configure 
  4. make && make instal  
tar jxvf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure
make && make instal
這裏請注意：
上面這一步是正常步驟，可是在centos5.7環境中，當你執行setuptools時可能會有如下報錯：
 
  1. Traceback (most recent call last): 
  2.   File "<string>", line 1, in <module> 
  3. zipimport.ZipImportError: can't decompress data; zlib not available  
Traceback (most recent call last):
  File "<string>", line 1, in <module>
zipimport.ZipImportError: can't decompress data; zlib not available
 
解決方法是在上面的configure以後，編輯Modules/Setup文件
找到下面這句，去掉註釋
 
  1. #zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz   
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
從新編譯安裝：
 
  1. make & make install   
make & make install
 
把系統自帶的2.4移除（依然會保留2.4版本：/usr/bin/python2.4）
 
  1. rm -f /usr/bin/python  
rm -f /usr/bin/python
把python執行軟鏈接鏈接到2.7
 
  1. ln -s /usr/local/bin/python2.7 /usr/bin/python  
ln -s /usr/local/bin/python2.7 /usr/bin/python
編輯yum命令，把路徑指明爲2.4，由於yum必須基於2.4版本
 
  1. sed -ie 's#/usr/bin/python$#/usr/bin/python2.4#g' /usr/bin/yum   
sed -ie 's#/usr/bin/python$#/usr/bin/python2.4#g' /usr/bin/yum
 
對應python2.7.3版本的是
下載後，執行
 
  1. sh setuptools-0.6c11-py2.7.egg  
sh setuptools-0.6c11-py2.7.egg
 
出現如下信息表示成功
 
  1. Processing setuptools-0.6c11-py2.7.egg 
  2. Copying setuptools-0.6c11-py2.7.egg to /usr/local/lib/python2.7/site-packages 
  3. Adding setuptools 0.6c11 to easy-install.pth file 
  4. Installing easy_install script to /usr/local/bin 
  5. Installing easy_install-2.7 script to /usr/local/bin 
  6.  
  7. Installed /usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg 
  8. Processing dependencies for setuptools==0.6c11 
  9. Finished processing dependencies for setuptools==0.6c11

安裝mysql相關包
 
  1. yum install MySQL-devel MySQL-client MySQL-shared-compat MySQL-shared  
yum install MySQL-devel MySQL-client MySQL-shared-compat MySQL-shared
下載好mysqldb
 
 
  1. tar xvzf MySQL-python-1.2.3.tar.gz 
  2. cd MySQL-python-1.2.3 
  3. vim site.cfg 
  4. 把上面的mysql_config路徑註釋刪除以及改爲實際路徑，若是不知道mysql_config在哪裏，運行命令：whereis mysql_config 
  5. python setup.py install  
tar xvzf MySQL-python-1.2.3.tar.gz
cd MySQL-python-1.2.3
vim site.cfg
把上面的mysql_config路徑註釋刪除以及改爲實際路徑，若是不知道mysql_config在哪裏，運行命令：whereis mysql_config
python setup.py install
 
安裝mysqldb總是報錯：
 
  1. running build 
  2. running build_py 
  3. copying MySQLdb/release.py -> build/lib.linux-x86_64-2.7/MySQLdb 
  4. running build_ext 
  5. building '_mysql' extension 
  6. gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -Dversion_info=(1,2,3,'final',0) -D__version__=1.2.3 -I/usr/include/mysql -I/usr/local/include/python2.7 -c _mysql.c -o build/temp.linux-x86_64-2.7/_mysql.o -g -pipe -m64 -fPIC -g -static-libgcc -fno-omit-frame-pointer -fno-strict-aliasing -DMY_PTHREAD_FASTMUTEX=1 
  7. 在包含自 _mysql.c：36 的文件中: 
  8. /usr/include/mysql/my_config.h:422:1: 警告：「HAVE_WCSCOLL」重定義 
  9. 在包含自 /usr/local/include/python2.7/Python.h：8 的文件中， 
  10.                  從 pymemcompat.h：10， 
  11.                  從 _mysql.c：29: 
  12. /usr/local/include/python2.7/pyconfig.h:890:1: 警告：這是先前定義的位置 
  13. gcc -pthread -shared build/temp.linux-x86_64-2.7/_mysql.o -L/usr/lib64 -lmysqlclient -lpthread -lm -lrt -ldl -o build/lib.linux-x86_64-2.7/_mysql.so 
  14. /usr/bin/ld: cannot find -lmysqlclient 
  15. collect2: ld 返回 1

/usr/bin/ld: cannot find -lmysqlclient

說找不到 mysqlclient ，真心不可能，我把mysql-devel 、 mysql-client、mysql-shared都裝上了。
 
只好從系統查找該文件，再創建軟鏈接
 
  1. find / -name 'libmysqlclient.so.*' 
  2. /usr/lib64/libmysqlclient.so.14 
  3. /usr/lib64/libmysqlclient.so.12 
  4. /usr/lib64/libmysqlclient.so.14.0.0 
  5. /usr/lib64/libmysqlclient.so.12.0.0 
  6. /usr/lib64/libmysqlclient.so.16 
  7. /usr/lib64/libmysqlclient.so.15 
  8. /usr/lib64/libmysqlclient.so.15.0.0 
  9. /usr/lib64/libmysqlclient.so.16.0.0  
find / -name 'libmysqlclient.so.*'
/usr/lib64/libmysqlclient.so.14
/usr/lib64/libmysqlclient.so.12
/usr/lib64/libmysqlclient.so.14.0.0
/usr/lib64/libmysqlclient.so.12.0.0
/usr/lib64/libmysqlclient.so.16
/usr/lib64/libmysqlclient.so.15
/usr/lib64/libmysqlclient.so.15.0.0
/usr/lib64/libmysqlclient.so.16.0.0
創建軟鏈接
 
  1. ln -s /usr/lib64/libmysqlclient.so.16.0.0 /usr/lib/libmysqlclient.so  
ln -s /usr/lib64/libmysqlclient.so.16.0.0 /usr/lib/libmysqlclient.so
 
再次install
 
  1. python setup.py install  
python setup.py install
 
若是這個步驟沒有報錯，表示基本完成
進入python命令行模式
 
  1. python  
python
再import MySQLdb，注意大小寫呢
 
  1. Python 2.7.3 (default, Dec 10 2012, 14:33:49) 
  2. [GCC 4.1.2 20080704 (Red Hat 4.1.2-51)] on linux2 
  3. Type "help", "copyright", "credits" or "license" for more information. 
  4. >>> import MySQLdb 
  5. /usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/_mysql.pyc, but /home/soft/MySQL-python-1.2.3 is being added to sys.path
